Correcteur d’orthographe et reformulateur — LanguageTool
Description from store

★ Détecte bien plus d'erreurs qu'un simple correcteur orthographique ;
★ Aucune identification nécessaire ;
★ Supporte plus de 25 langues (liste exhaustive tout en bas) ;
★ Fonctionne sur presque tous les sites, même Gmail, Facebook ou Twitter.

Avec ce module, le correcteur LanguageTool vous accompagne partout sur internet. Non content de détecter toutes les fautes d'orthographe comme un simple dictionnaire, LanguageTool détecte les fautes de grammaire (accord, répétitions, homophones, etc.), de conjugaison ou de style (anglicismes, formules éculées, etc.) !

LanguageTool est conçu pour être très simple d'utilisation, le texte que vous tapez est vérifié automatiquement, et un simple clic ou raccourci clavier permet d'appliquer la correction désirée. Le module LanguageTool fonctionne sur la quasi-totalité des sites internet, y compris les réseaux sociaux comme Facebook, Twitter ou LinkedIn, ou n'importe quel service de messagerie en ligne (Gmail, Orange, etc.).

Avec LanguageTool notre but est de donner à l'utilisateur un vérificateur complet et un outil de relecture fiable qui lui permettent de contrôler ses écrits.
LanguageTool est un module incontournable aussi bien pour votre langue maternelle que pour les langues étrangères. Les corrections grammaticales et orthographiques se font en fonction des variantes de langues, en différenciant par exemple l'anglais états-unien de l'anglais britannique.

LanguageTool comprend également une fonction de dictionnaire personnel pour les exceptions ou les mots que vous utilisez fréquemment qui seraient inconnus des dictionnaires traditionnels. Une fois ajoutés, LanguageTool reconnaîtra ces mots dans toutes vos futures vérifications.

Contrairement à Antidote, Grammalecte, Grammarly, QuillBot ou la plupart des alternatives, LanguageTool fonctionne avec énormément de langues, tout en offrant la plupart de leurs fonctionnalités !

Le respect de votre vie privée est important pour nous : cette extension vérifie vos textes en les envoyant sur le site https://languagetool.org via une connexion chiffrée sécurisée. Nous ne stockons aucun des textes que vous vérifiez, ni votre adresse IP. Cette extension ne nécessite aucune création de compte pour fonctionner.

Notre politique de vie privée est disponible à cette adresse : http://languagetool.org/privacy/

Liste des langages supportés : Français, Anglais (Australien, Canadien, Britannique, Nouvelle-Zélande, Sud-Africain, Américain), Allemand (Autrichien, Allemand, Suisse), Asturien, Biélorusse, Breton, Catalan (et Valencien), Chinois, Danois, Espagnol, Espéranto, Galicien, Grec, Italien, Japonais, Khmer, Néerlandais, Perse, Polonais, Portugais (Brésilien, Portugais, Angolais, Mozambicain), Roumain, Russe, Slovaque, Slovène, Suédois, Tagalog, Tamil, Ukrainien, Arabe.

Long-term user since 2019, but recent update now forcing users to pay for a premium subscription, otherwise it will stop working after the trial ends.

Awful greedy company made a cheap move on all it's free users and honestly I will be telling everyone I know how garbage you really are and how over the last year you have been getting worse and worse.
Matt Skujins
Once was good... but now the company got greedy.

Forcing AI into a free extension, then forcing the users to pay for that AI since it costs too much to run is really a new low. The extension ran fine while being community driven for years, but they couldn't pass up the chance to use AI, and now that it's not profitable, the user has to pay for premium...
Sachin Bahal
Using the extension is no longer free as of Jan 13th 2026, it's now part of a their premium subscription (which is paid), it's kind of a shady move to completely remove free access of the browser extension.
Delta
they're making it so you have to pay for it to use as an extension now??? I don't even know where I can find something as soon as this one for me and now I can't use it-
Harry Looney
Love this app. I am a terrible typist so it helps me greatly!

Your work is not a unique value, but merely a tool for those who don’t want to figure things out themselves. Users are learning, and soon many of your functions will become unnecessary: competitors will take them over. I won’t mind if they even slap on some ads — I’ll watch with pleasure. Developers often «bury» their projects along with their career ambitions — this cycle is inevitable.
Eric Ketzer
So in a few days, we won't be able to use it unless we pay for the Premium. Holy s**it....
Bonnie Scot
Used LT for as long as I can remember. Good few years anyway. To now make it premium (paid) to use the browser extention is REALLY below the belt. Lots of FREE alternatives out there. LT was just my go-to. It's my guess, they will live to REGRET that descision. Uninstalled.

my top 5 app

Works very nice with multiple languages.

Incredible tool.
Toni Bechlievski
worked prety well, but they decided to offer only paid version so that is a no go for me. sorry
CheekyRand0m
Does what it says (with a cherry on top). A great alternative to most, if not ALL grammar checkers, spell checkers, paraphrasers, et cetera. Would recommend to an Apple or Google One user. Might need to loosen the Basic restrictions so you can squeeze at least some revenue from Basic users. 4 out of 5 stars.

Invades privacy, isn't free anymore and requires a premium subscription to work, Harper is much better and also truely opensource.
Kyd Ev
Forcing a paid only version to include AI. That is just shameful. There's not even a less expensive AI-free version, that I WOULD HAVE SUBSCRIBED TO IF LESS EXPENSIVE. Now it's just hilariously expensive.
Mohamed Laraiche
Bad Marketing move you did. wasn't clean to "kick-out" user with this way even if im able to pay i won't pay with this way. specially there is TONS of tools doing the same. little or more not asking payment with this way :). good luck and try to check this way you put the limitaiton you will drop lot
Evelina Nikolova
made is paid only, subscription price is too high for what youre actually getting
OlangaHD
It was a great service until today, when the message appeared that it can now only be used with payment. I hope this decision will be reversed once more than ninety-five percent of users uninstall the extension. It’s a real shame, but it is what it is. Tip for anyone who now needs a free alternative: take a look at QuillBot. EDIT: They do actually link to QuillBot after uninstalling, which I find pretty fair.

Now - paid only. Sorry there is a sea of free spellcheckers, bye.
Wallace Dittman
Be careful with this tool. Since they've switched to the paid subscription mode, it still disables your native browser grammar checker if you have LanguageTool installed. It means you may inadvertently skip a mistake. Delete it immediately, if you are not planning on switching to the paid model.
Filip Korpet
With mandatory premium, it's time to look for samo more healthy alternatives
Darrell Dabney-Carter
This Gemini newsiest tool addition and AI code assistant have improved significantly and added much-needed value to my project.
Reynaldo
Great app to learn new concepts for English learners.
Ruben van hee
I was looking for a spellcheck extension that was just that, no AI recommendations on how to phrase my own sentences, etc. This was it, no AI slop and bloat, just spellcheck. And it supports my main languages: Dutch, French, English and German. Recently has gone paid to use the extension and/or desktop app, but to me this is understandable considering the server costs they occur. So far they have been supported by the EU, so it might be this support is waning and they need to fund themselves. The API itself is still open source and available on github so, if you know what you're doing, and can follow instructions, you can still run the extension locally: https://languagetool.org/dev

Suddenly not free anymore. Bye bye
Mandeep Sachdeva
Works perfectly and so easy to use I love the Chrome extension except the one problem I have is that app doesn't support most writing platforms.

Now only reserved for paid users, power and money hungry.

Developers are most likely paying, botting, and/or making positive reviews for this dog water extension. Probably trying to bury the bad reviews and keep the stars high so people think it's good and worth paying for.

not free anymore

I like it for the most part, I did end up buying a yearly subscription, it's a lot less than Grammarly although Grammarly is better, imo, but its 3x the price. I would like to see an option to include certain words and their grammar in the dictionary. Some word I want to be capitalized and I don't like to continuously deal with the Grammar checker to clear the "error" of capitalization.
